Description

Technical Field

[0001] This utility model relates to the field of cleanroom cloth processing technology, specifically a cleanroom cloth slitting machine for precise width determination. Background Technology

[0002] With the rapid development of industries such as electronics, semiconductors, and medical devices, the demand for cleanroom wipes is increasing, and higher requirements are being placed on the slitting accuracy and efficiency of cleanroom wipes. Existing cleanroom wipe slitting machines are not precise enough in controlling the slitting width, often relying on the operator's experience and visual estimation, lacking precise positioning and adjustment devices. This results in large errors in the width of the slitting cleanroom wipes, failing to meet the requirements of high-precision production. For example, in some electronic component cleaning scenarios where cleanroom wipe dimensions are strictly required, inaccurate width cleanroom wipes may affect the cleaning effect or even damage the components. Some slitting machines have complex blade installation structures, requiring a lot of time and effort to replace the blades. Moreover, the blades are prone to loosening during use, affecting the continuity and quality of slitting, increasing equipment maintenance costs and downtime. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0029] Precise width-determining cleanroom cloth slitting machine, such as Figures 1-3As shown, the device includes a slitting base 10 for processing cleanroom wipes. Two ends of the slitting base 10 are equipped with synchronously operating hydraulic cylinders 20. A top frame 30 is installed between the piston rods 21 of the two sets of hydraulic cylinders 20. Several sets of adjustable precision width-fixing slides 40 are mounted on the top frame 30. Each precision width-fixing slide 40 has a replaceable slitting blade 50 mounted at its bottom. Locking bolts 41 for securing the precision width-fixing slides 40 are mounted on their tops. The replaceable slitting blade 50 includes a fixing frame 51 and a slitting blade. 57. A hollow groove 54 is provided inside the fixed frame 50. A lifting movable block 55 is slidably installed in the hollow groove 54. The lifting movable block 55 is connected to the top of the slitting blade 57 through a blade holder 56. A return spring 58 is installed between the lifting movable block 55 and the top of the hollow groove 54. The slitting base 10 provides a stable foundation for the processing of cleanroom cloth. The hydraulic cylinders 20 that work synchronously at both ends can drive the piston rod 21 to extend and retract, thereby adjusting the height of the top frame 30 to adapt to different processing needs. Several sets of adjustable precision width-fixing slides 40 are installed on the top frame 30. With the help of the locking bolts 41 on the top, the width can be precisely fixed and locked to ensure the accuracy of the slitting width. Each set of precision width-fixing slides 40 has a replaceable slitting knife 50 installed at the bottom. The hollow groove 54 opened in the fixed frame 51 provides sliding space for the lifting movable block 55. The lifting movable block 55 and the slitting knife 57 are connected through the knife holder 56. Under the action of the return spring 58, a stable cutting force can be maintained during the slitting operation.

[0030] It is worth noting that the outer walls on both sides of the top frame 30 are equipped with scale lines 31 for precise reading, which allows the operator to intuitively read and adjust the position of the precision width-fixing slide 40, thereby achieving precise control and adjustment of the slitting width and improving the accuracy and efficiency of the operation.

[0031] Furthermore, the cross-section of the precision width-fixing slide 40 is matched with the cross-sectional dimensions of the top frame 30, and the two are in an interference fit, which makes the precision width-fixing slide 40 more stable when sliding on the top frame 30, reducing shaking and deviation, and further improving the accuracy and stability of the slitting operation.

[0032] Specifically, the bottom of the precision width-fixing slide 40 is provided with a positioning slot 42, and the top of the fixing frame 51 is equipped with a plug 52 that is compatible with the size of the positioning slot 42 and can be inserted and mated, so that the replaceable slitting knife 50 can be installed and disassembled conveniently and quickly, while ensuring the stability and accuracy of the installation, improving work efficiency and the convenience of replacing the blade.

[0033] In addition, the two sides of the fixing frame 51 are symmetrically provided with fixing ears 53 for connecting to the bottom surface of the precision width-fixing slide 40. The fixing ears 53 are connected to the bottom surface of the precision width-fixing slide 40 by fixing screws, which enhances the connection stability and firmness between the replaceable slitting knife 50 and the precision width-fixing slide 40, prevents loosening and falling off that may occur during operation, and ensures the safety and stability of operation.

[0034] The working principle of this precision width-fixing cleanroom cloth slitting machine:

[0035] First, place the lint-free cloth on the slitting base 10 and ensure it is flat. Then, according to the required slitting width, adjust the position of the precision width-fixing slide 40 on the top frame 30 by observing the scale lines 31 on both sides of the outer wall of the top frame 30. Since the inner cross-section of the precision width-fixing slide 40 is compatible with the cross-sectional dimensions of the top frame 30 and has an interference fit, the stability and accuracy during the sliding process can be guaranteed. After adjusting the position, tighten the locking bolt 41 on the top of the precision width-fixing slide 40 to fix it.

[0036] Next, the replaceable slitting knife 50 is installed at the bottom of the precision width-fixing slide 40; first, the plug 52 at the top of the fixing bracket 51 is inserted into the positioning slot 42 at the bottom of the precision width-fixing slide 40 for initial positioning, and then it is firmly connected by the fixing screw on the fixing side ear 53.

[0037] Next, start the hydraulic cylinder 20. The piston rod 21 of the hydraulic cylinder 20 drives the top frame 30 to descend, so that the slitting knife 57 contacts the cleanroom cloth and pulls the cleanroom cloth to slit it. After slitting is completed, the hydraulic cylinder 20 drives the top frame 30 to rise and remove the slit cleanroom cloth. If it is necessary to replace the knife or adjust the slitting width, repeat the above steps.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
